Apache Ranger简介

Apache Ranger提供一个集中式安全管理框架, 并解决授权和审计。它可以对Hadoop生态的组件如HDFS、Yarn、Hive、Hbase等进行细粒度的数据访问控制。通过操作Ranger控制台,管理员可以轻松的通过配置策略来控制用户访问权限。Ranger优点:

Apache Ranger安装

官方文档:

前置准备

首先准备好Java和Maven环境:

[root@hadoop ~]# java -version
java version "1.8.0_261"
Java(TM) SE Runtime Environment (build 1.8.0_261-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.261-b12, mixed mode)
[root@hadoop ~]# mvn -v
Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)
Maven home: /usr/local/maven
Java version: 1.8.0_261, vendor: Oracle Corporation, runtime: /usr/local/jdk/1.8/jre
Default locale: zh_CN, platform encoding: UTF-8
OS name: "linux", version: "3.10.0-1062.el7.x86_64", arch: "amd64", family: "unix"
[root@hadoop ~]# 

安装一个MySQL数据库,我这里使用的是我本地的数据库:

C:\Users\Administrator>mysql --version
mysql  Ver 8.0.21 for Win64 on x86_64 (MySQL Community Server - GPL)

搭建一个Hadoop环境,注意Hadoop的版本一定要 >= 2.7.1,因为我之前尝试过2.6.0版本的Hadoop无法与Ranger整合成功,本文使用的是2.8.5版本:

[root@hadoop ~]# echo $HADOOP_HOME
/usr/local/hadoop-2.8.5
[root@hadoop ~]# 

Ranger依赖了MySQL作为状态存储,所以需要准备一个MySQL的驱动包:

[root@hadoop ~]# ls /usr/local/src |grep mysql
mysql-connector-java-8.0.21.jar
[root@hadoop ~]# 

编译Ranger源码

到官网上下载源码包:

需要注意Ranger与Hadoop的对应版本,如果你安装的Hadoop是2.x的,那么Ranger需要采用2.x以下的版本。如果你安装的Hadoop是3.x的,那么Ranger需要采用2.x以上的版本。例如,我这里安装的Hadoop版本是2.8.5,所以选择1.2.0版本的Ranger:

[root@hadoop ~]# cd /usr/local/src
[root@hadoop /usr/local/src]# wget https://mirror-hk.koddos.net/apache/ranger/1.2.0/apache-ranger-1.2.0.tar.gz

解压源码包:

[root@hadoop /usr/local/src]# tar -zxvf apache-ranger-1.2.0.tar.gz

进入解压后的目录:cd apache-ranger-1.2.0,修改该目录下的pom文件,将仓库相关配置都给注释掉:

<!--
    <repositories>
        <repository>
            <id>apache.snapshots.https</id>
            <name>Apache Development Snapshot Repository</name>
            <url>https://repository.apache.org/content/repositories/snapshots</url>
            <snapshots>
                <enabled>true</enabled>
            </snapshots>
        </repository>
        <repository>
            <id>apache.public.https</id>
            <name>Apache Development Snapshot Repository</name>
            <url>https://repository.apache.org/content/repositories/public</url>
            <releases>
                <enabled>true</enabled>
            </releases>
            <snapshots>
                <enabled>false</enabled>
            </snapshots>
        </repository>
    <repository>
      <id>repo</id>
      <url>file://${basedir}/local-repo</url>
      <snapshots>
         <enabled>true</enabled>
      </snapshots>
  </repository>
    </repositories>
-->

完成以上的修改后,使用maven命令进行编译打包:

[root@hadoop /usr/local/src/apache-ranger-1.2.0]# mvn -DskipTests=true clean package assembly:assembly

经过一段漫长的等待后,编译打包完成将输出如下信息:

[root@hadoop /usr/local/src/apache-ranger-1.2.0]# 

安装Ranger Admin

将ranger admin的安装包解压到合适的目录下,我这里习惯放到/usr/local

[root@hadoop /usr/local/src/apache-ranger-1.2.0]# tar -zxvf target/ranger-1.2.0-admin.tar.gz -C /usr/local/

进入解压后的目录,目录结构如下:

[root@hadoop /usr/local/src/apache-ranger-1.2.0]# cd /usr/local/ranger-1.2.0-admin/
[root@hadoop /usr/local/ranger-1.2.0-admin]# ls
bin                    contrib  dba_script.py           ews                 ranger_credential_helper.py  set_globals.sh           templates-upgrade   upgrade.sh

[root@hadoop /usr/local/ranger-1.2.0-admin]# 

配置安装选项:

[root@hadoop /usr/local/ranger-1.2.0-admin]# vim install.properties
# 指定MySQL驱动包所在的路径
SQL_CONNECTOR_JAR=/usr/local/src/mysql-connector-java-8.0.21.jar

# 配置root用户名密码以及MySQL实例的连接地址
db_root_user=root
db_root_password=123456a.
db_host=192.168.1.11

# 配置访问数据库的用户名密码
db_name=ranger_test
db_user=root
db_password=123456a.

# 指定审计日志的存储方式
audit_store=db
audit_db_user=root
audit_db_name=ranger_test
audit_db_password=123456a.

在MySQL中创建ranger数据库:

create database ranger_test;

由于我这里使用的是MySQL8.x,需要修改一下数据库相关的脚本,不是MySQL8版本的可以跳过这一步。打开dba_script.pydb_setup.py文件,搜索如下内容:

-cstring jdbc:mysql://%s/%s%s

将其全部修改为如下所示,主要是添加JDBC的serverTimezone连接参数:

-cstring jdbc:mysql://%s/%s%s?serverTimezone=Asia/Shanghai

然后执行如下命令开始安装ranger admin:

[root@hadoop /usr/local/ranger-1.2.0-admin]# ./setup.sh

报错解决

安装过程中如果报如下错误:

SQLException : SQL state: HY000 java.sql.SQLException: Operation CREATE USER failed for 'root'@'localhost' ErrorCode: 1396

SQLException : SQL state: 42000 java.sql.SQLSyntaxErrorException: Access denied for user 'root'@'192.168.1.11' to database 'mysql' ErrorCode: 1044

解决方式,就是在MySQL中执行如下语句:

use mysql;
flush privileges;
grant system_user on *.* to 'root';
drop user'root'@'localhost';
create user 'root'@'localhost' identified by '123456a.';
grant all privileges on *.* to 'root'@'localhost' with grant option;

drop user'root'@'192.168.1.11';
create user 'root'@'192.168.1.11' identified by '123456a.';
grant all privileges on *.* to 'root'@'192.168.1.11' with grant option;
flush privileges;

如果报如下错误:

SQLException : SQL state: HY000 java.sql.SQLException: This function has none of DETERMINISTIC, NO SQL, or READS SQL DATA in its declaration and binary logging is enabled (you *might* want to use the less safe log_bin_trust_function_creators variable) ErrorCode: 1418

解决方式:

set global log_bin_trust_function_creators=TRUE;
flush privileges;

如果报如下错误:

SQLException : SQL state: HY000 java.sql.SQLException: Cannot drop table 'x_policy' referenced by a foreign key constraint 'x_policy_ref_role_FK_policy_id' on table 'x_policy_ref_role'. ErrorCode: 3730

解决方式:删除ranger库中所有的表,再重新执行./setup.sh

安装完成后最终会输出:

Installation of Ranger PolicyManager Web Application is completed.

启动ranger admin

修改配置文件,配置数据库连接密码和jdbc url时区参数:

[root@hadoop /usr/local/ranger-1.2.0-admin]# vim conf/ranger-admin-site.xml
...

<property>
        <name>ranger.jpa.jdbc.url</name>
        <value>jdbc:log4jdbc:mysql://192.168.1.11/ranger_test?serverTimezone=Asia/Shanghai</value>
        <description />

        <name>ranger.jpa.jdbc.password</name>
        <value>123456a.</value>
        <description />
</property>

...

修改审计存储相关配置:

[root@hadoop /usr/local/ranger-1.2.0-admin]# vim conf/ranger-admin-default-site.xml
...

<property>
        <name>ranger.jpa.audit.jdbc.url</name>
        <value>jdbc:log4jdbc:mysql://192.168.1.11:3306/ranger_test?serverTimezone=Asia/Shanghai</value>

Ranger HDFS Plugin安装

解压hdfs plugin的安装包到合适的目录下:

[root@hadoop ~]# mkdir /usr/local/ranger-plugin
[root@hadoop ~]# tar -zxvf /usr/local/src/apache-ranger-1.2.0/target/ranger-1.2.0-hdfs-plugin.tar.gz -C /usr/local/ranger-plugin
[root@hadoop ~]# cd /usr/local/ranger-plugin/
[root@hadoop /usr/local/ranger-plugin]# mv ranger-1.2.0-hdfs-plugin/ hdfs-plugin

进入解压后的目录,目录结构如下:

[root@hadoop /usr/local/ranger-plugin/hdfs-plugin]# ls
disable-hdfs-plugin.sh  enable-hdfs-plugin.sh  install  install.properties  lib  ranger_credential_helper.py  upgrade-hdfs-plugin.sh  upgrade-plugin.py
[root@hadoop /usr/local/ranger-plugin/hdfs-plugin]# 

配置安装选项:

[root@hadoop /usr/local/ranger-plugin/hdfs-plugin]# vim install.properties
# 指定ranger admin服务的访问地址
POLICY_MGR_URL=http://192.168.243.161:6080
# 配置仓库名称,可自定义
REPOSITORY_NAME=dev_hdfs
# 配置hadoop的安装目录
COMPONENT_INSTALL_DIR_NAME=/usr/local/hadoop-2.8.5

# 配置用户和用户组
CUSTOM_USER=root
CUSTOM_GROUP=root

执行如下脚本开启hdfs-plugin

[root@hadoop /usr/local/ranger-plugin/hdfs-plugin]# ./enable-hdfs-plugin.sh 

脚本执行成功后,会输出如下内容:

Ranger Plugin for hadoop has been enabled. Please restart hadoop to ensure that changes are effective.

重启Hadoop:

[root@hadoop ~]# stop-all.sh 
[root@hadoop ~]# start-all.sh

验证权限控制

到Ranger Admin上添加hdfs service,这里的Service Name需与配置文件中的配置所对应上:


image.png

填写相应信息:


image.png

填写完成后,到页面底部点击“Test Connection”测试能否正常连接,确认可以正常连接后点击“Add”完成新增:


image.png

等待一会后,到 “Audit” -> “Plugins” 页面查看有没有发现hdfs插件,如果没有的话代表插件没有启用成功。正常情况如下:


image.png

确认hdfs插件整合成功后,在hdfs中创建一些测试目录和文件:

[root@hadoop ~]# hdfs dfs -mkdir /rangertest1
[root@hadoop ~]# hdfs dfs -mkdir /rangertest2
[root@hadoop ~]# echo "ranger test" > testfile
[root@hadoop ~]# hdfs dfs -put testfile /rangertest1
[root@hadoop ~]# hdfs dfs -put testfile /rangertest2

然后到Ranger Admin上添加Ranger的内部用户,“Settings” -> “Add New User”,填写用户信息:


image.png

接着添加权限策略,“Access Manager” -> “dev_hdfs” -> “Add New Policy”,配置权限策略所作用的用户、目录等信息:


image.png

拉到底部点击“Add”完成添加后,可以看到新增了一条策略配置:


image.png

回到操作系统,添加并切换到hive用户,测试能否正常读取目录、文件:

[root@hadoop ~]# sudo su - hive
[hive@hadoop ~]$ hdfs dfs -ls /
Found 2 items
drwxr-xr-x   - root supergroup          0 2020-11-12 13:48 /rangertest1
drwxr-xr-x   - root supergroup          0 2020-11-12 13:48 /rangertest2
[hive@hadoop ~]$ hdfs dfs -ls /rangertest1
Found 1 items
-rw-r--r--   1 root supergroup         12 2020-11-12 13:48 /rangertest1/testfile
[hive@hadoop ~]$ hdfs dfs -cat /rangertest1/testfile
ranger test
[hive@hadoop ~]$ hdfs dfs -ls /rangertest2
Found 1 items
-rw-r--r--   1 root supergroup         12 2020-11-12 13:48 /rangertest2/testfile
[hive@hadoop ~]$ 

通过查看目录信息可以看到rangertest1rangertest2目录的权限位是:drwxr-xr-x,也就说除root外的用户是没权限对这两个目录进行写操作的。

但此时测试写操作,会发现hive用户能够正常往rangertest1目录添加文件,但往rangertest2目录添加文件就会报错,因为在Ranger中我们只赋予了hive用户对rangertest1目录的读写权限:

[hive@hadoop ~]$ echo "this is test file 2" > testfile2
[hive@hadoop ~]$ hdfs dfs -put testfile2 /rangertest1
[hive@hadoop ~]$ hdfs dfs -put testfile2 /rangertest2
put: Permission denied: user=hive, access=WRITE, inode="/rangertest2":root:supergroup:drwxr-xr-x
[hive@hadoop ~]$ 

如果我们想禁止hive用户对rangertest2目录的所有操作,那么就可以新增一条拒绝策略,“Resource Path”选择rangertest2目录,并且在“Deny Conditions”一栏中勾选需要deny的权限即可:

image.png

策略生效后,此时hive用户访问rangertest2目录就会提示权限拒绝了:

[hive@hadoop ~]$ hdfs dfs -ls /rangertest2
ls: Permission denied: user=hive, access=EXECUTE, inode="/rangertest2"
[hive@hadoop ~]$ hdfs dfs -cat /rangertest2/testfile
cat: Permission denied: user=hive, access=EXECUTE, inode="/rangertest2/testfile"
[hive@hadoop ~]$ 

至此,Ranger对HDFS的权限控制也验证通过了。除此之外,你也可以进行其他的测试。


Ranger Hive Plugin安装

首先需要搭建好Hive环境,可以参考下文:

为了与Hadoop和Ranger版本保持兼容,本文使用的Hive版本是2.3.6

[root@hadoop ~]# echo $HIVE_HOME
/usr/local/apache-hive-2.3.6-bin
[root@hadoop ~]# 

解压hive plugin的安装包到合适的目录下:

[root@hadoop ~]# tar -zxvf /usr/local/src/apache-ranger-1.2.0/target/ranger-1.2.0-hive-plugin.tar.gz -C /usr/local/ranger-plugin/
[root@hadoop /usr/local/ranger-plugin]# mv ranger-1.2.0-hive-plugin/ hive-plugin

进入解压后的目录,目录结构如下:

[root@hadoop /usr/local/ranger-plugin]# cd hive-plugin/
[root@hadoop /usr/local/ranger-plugin/hive-plugin]# ls
disable-hive-plugin.sh  enable-hive-plugin.sh  install  install.properties  lib  ranger_credential_helper.py  upgrade-hive-plugin.sh  upgrade-plugin.py
[root@hadoop /usr/local/ranger-plugin/hive-plugin]# 

配置安装选项:

[root@hadoop /usr/local/ranger-plugin/hive-plugin]# vim install.properties
# 指定ranger admin服务的访问地址
POLICY_MGR_URL=http://192.168.243.161:6080
# 配置仓库名称,可自定义
REPOSITORY_NAME=dev_hive
# 配置hive的安装目录
COMPONENT_INSTALL_DIR_NAME=/usr/local/apache-hive-2.3.6-bin

# 配置用户和用户组
CUSTOM_USER=root
CUSTOM_GROUP=root

执行如下脚本开启hive-plugin

[root@hadoop /usr/local/ranger-plugin/hive-plugin]# ./enable-hive-plugin.sh 

脚本执行成功后,会输出如下内容:

Ranger Plugin for hive has been enabled. Please restart hive to ensure that changes are effective.

重启Hive:

[root@hadoop ~]# jps
8258 SecondaryNameNode
9554 EmbeddedServer
8531 NodeManager
13764 Jps
7942 NameNode
11591 RunJar
8040 DataNode
8428 ResourceManager
[root@hadoop ~]# kill -15 11591
[root@hadoop ~]# nohup hiveserver2 -hiveconf hive.execution.engine=mr &

验证权限控制

到Ranger Admin上添加hive service,这里的Service Name需与配置文件中的配置所对应上:


image.png

填写相应信息,并点击“Add”完成新增:


image.png

等待一会后,到 “Audit” -> “Plugins” 页面查看有没有探测到该hive插件,如果没有的话代表插件没有启用成功。正常情况如下:


image.png

确认hive插件整合成功后,添加权限策略,“Access Manager” -> “dev_hive” -> “Add New Policy”,配置权限策略所作用的用户、库、表、列等信息:


image.png

回到操作系统上,切换到hive用户,并通过beeline进入Hive的交互终端:

[root@hadoop ~]# sudo su - hive
上一次登录:四 11月 12 13:53:53 CST 2020pts/1 上
[hive@hadoop ~]$ beeline -u jdbc:hive2://localhost:10000 -n hive

测试权限,可以看到除了show tables外的操作都被拒绝了:

0: jdbc:hive2://localhost:10000> show tables;
+-----------------+
|    tab_name     |
+-----------------+
| hive_wordcount  |
+-----------------+
